take a 1/2" drive 6" long extension to jack up next to the motor mount, and then take the motor mount bolt out of the bottom, lift the engine up.
you will also need to take out the transmission dipstick tube, just make sure it goes back in before you bolt the header down completely
Also only use Ford's steal gaskets, they are better then anything your headers come with. You can try and reuse your factory ones, or buy a new set of 4 for around 120 bucks
good luck.

you should be able to get all the studs out without that much space. If you look at the end of the stud there is like a 5.5mm head on it. Put a short 1/4" drive socket on it and take it out if the stud doesnt come out with the nut still on it.
As far as jacking up the motor, you shouldnt be able to go that far up with firewall and transmission clearance issues. We were able to get the long tubes in with only going up 1" maybe 1.5"

It is normal for headers to be larger than the exhaust port. As long as the gasket is not blocking the exhaust port, it is okay for it to block the header opening.
Edit:
I just noticed that the header is unblocked on one side. I would measure to verify that the header fully covers the top of the exhaust port.

Thanks for the reply, i understand this, but , the part iam worried about is that the factory header gasket has that "crush area" around the port opening. Iam afraid if i install it, the gasket will never seal properly because the bottom of the gasket never gets crushed. Does everybody else run these gaskets with out problem? Also, when i picked this stuff up i told them i wanted the new stainless steel studs and nuts, and he said , "Oh yea, i know", so when i got home, i checked them with a magnet, yep mild steel, so im kinda dead in the water now. lol

I used the gaskets that came with the OBX kit....
I used the original factory studs and nuts.....
No problems so far.
I jacked up the passenger side of the engine.
I took off the starter.
I took out the transmission dip stick(and replaced before bolting the header on).
I think I hit all the questions in this thread....
